MEANS FOR CLEANING CARDS.

Specification of Letters Patent.

Patented June 24, 1919.

To all whom it may concern Be it known that I, LOREN W. PENNEY, ofNewton, in the county of Middlesex and State of Massachusetts, a citizenof the United States, have invented a new and useful Improvement inMeans for Cleaning Cards, of which the following is a specification.

The object of my invention is to provide a simple and eflective meansfor stripping the cylinder or dofi'er of a carding engine. Heretoforeattempts have been made to strip the card of its collected fibers, etc.by means such as a rotary brush which is applied by hand to the card, bya small vacuum nozzle traveling transverse of the machine in closerelation to the card so as to draw the fibers, etc., out by suction, bya device similar in construction by which the fibers are blown from thecard by a strong air blast and then are carried away by suction, or by astrip.- ping brush which is itself stripped by a second rotary stripperwhich is cleaned by suction, etc. These devices are all of them more orless successful, but none of them is entirely so.

My invention consists in a cylindrical cleaning brush which may berotated by power and which may be supported on the carding enginebetween the cylinder and the doifer so that it may be ad usted to cleaneither at will. It is supported in close relation to a nozzle connectedby a pipe with a vacuum pump or exhaust fan so that the indraft of airfrom the nozzle will draw the fibers from the teeth of the cleaningbrush which are shaped so as not to become clogged.

My invention will be understood by reference to the drawings where it isshown in its referred form;

Figure 1 being a nism embodying my the driving shaft of ing in section.

Fig. 2 is a corresponding View showing a portion of the doifer, thecleaning brush and the vacuum pipe in section;

side elevation of mechainvention, the end of the cleaning brush be- Fig.3 being a vertical section taken through the cleaning brush on line 33of Fig. 1.

Only one side of the carding engine is shown and only so much thereof asis necessary to explain my invention.

A is a cylinder which is inclosed in a casas required.

ing A of the usual character and in the usual way, and carries the wirecard clothing a. B indicates the dofier which is also inclosed in itsusual portion B of the easing. To the casing A on each side of theengine is pivotally attached at c an arm G which has at its outer endbearings C in which is mounted the shaft C carrying the stripper C Thesearms G are slotted as at c and within the slot in each arm is aneccentric d mounted on a shaft D which extends across the machine and ishung in brackets D (of which only one is shown) and which are adjustablymounted on opposite sides of the casing A being held thereto by a bolt03. These eccentrics (Z being fast to the shaft D, the turning of theshaft-by the handle D carries the rocking arms C together with thestripper C from the position in Fig. 2 where the stripper engages thedofi'er B, into a position to engage the cylinder A At the end of theshaft C is mounted a pulley C by means of which and a suitable belt,power is applied to the shaft C to rotate the stripper C The shaft Dalso carries a disk D having notches d located at proper points thereonso that the shaft D may be locked to hold the cleaning brush either incontact with the doffer or with the cylinder or in a neutral position,these notches being engaged by a lever D having a detent d thereonadapted to engage either one of these notches This lever is pivoted tothe bracket D at 01*.

E is a pipe carrying a nozzle E which eX- tends across the cardingengine, its length corresponding with the width of the stripper itsopening being of a suitable width to secure an effective indraft. To theend of this nozzle is attached a cover 6 which projects therefromcovering part of the upper surface of the stripper and extending towardthe cylinder sufliciently far nearly to engage the periphery of thecylinder when the stripper is thrown over to clean the cylinder. E is adamper by which the pipe E may be closed and E is a hinged door closinga hand-hole in the nozzle E and serving to receive waste to be thrown inby hand.

The nozzle E is mounted on the rocking or swinging carrier or framewhich supports the stripping roll C so that said nozzle will move withsaid stripping roll when the latter is moved into engagement either withthe dolfer or the carding cylinder, and

the casing or cover 6 is of such form as to permit the teeth of the saidstripping roll to engage the carding cylinder as well as the doffer.

The stripper C clothing somewhat that of the cylinder prising wire teethhas a covering of card similar in character to and the doffer, butcomwhich are very much longer than those of the cylinder and doifcr andof somewhat different shape, and this card clothing is arranged upon thestripper roll to which it is attached so that the ends of its teetharesubstantially radial to the axis of the brush comprising said teethor wires. It will thus be seen that anything which is carried by thesewires, when it reaches the nozzle E may easily be withdrawn from thebrush by the indraft and carried up through thepipe.

The operation of this device understood. The lever D draw the detent (Zwill be easily is lifted to withfrom the notch (Z in which it is restingand the handleof the shaft D is turned so as to turn the eccentric (Zwhich throws the arm C toward either rotary member, the doifer or thecylinder, as the case may be, after which the lever D is depressed tolock the shaft D. If the stripper engages the doffer, as shown in Fig.2, it being rotated in the direction of the arrow (see Fig. :2), stripsthe doffer carrying the fiber, dirt, etc.,- around until it comes infront of the nozzle when the inward draft draws off from the straight orradial ends of the teeth of the stripper the material collected there,the damper E of course being open'at this time. If it is desired tostrip the cylinder, the shaft D is turned, thus turning the eccentric (Zso as to throw the armCto the right (see F ig.2) and cause the stripperto engage the clothing a on the cylinder A when the same operation takesplace, the cylinder being cleaned and the collection from it beingcarried around by the "stripper to the nozzle E and withdrawn from theteeth of the brush by the vacuum. WVhen the engine has been entirelycleaned the shaft D is unlocked and turned so as to turn the eccentric(Z to bring the brush into neutral position where it is locked by theengagement of the projection (Z with its appropriate notch (Z It isdesirable to support the rear end of the nozzle upon a rest 6 mounted ontop of the casing B and extending the length of the nozzle, 2'. 6., thewidth of the casing, to present the nozzle at a proper angle to thestripper.

In practice it is also desirable that the stripper shall be rotated at aspeed considerably faster than the cylinder, say three times or more asfast. Vith such speed centrifugal force will act to assist in theremoval of the dirt and fly from the stripper especially in view of theshape of the teeth of the stripper, the outer ends 0 of which, it willbe noted, are shown as straight, 6., approximately radial to the axis ofthe These ends pick up the dirt and stripper. fiyfrom the card or thedofl'er which when they reach the nozzle, being held on these radialportions of the teeth, are drawn off by the exhaust without obstruction,being held near the periphery of the stripper by centrifugal force.

In. using the term rotary member I mean any rotary member such as thecylinder or dofier which acts directly upon the material upon which themachine is work ing.

The pipe. E connects with a vacuum pump or exhaust fan located in anyconvenient place, the dirt and fly being taken care of in any convenientmanner.

Other embodiments of this invention will occur to those skilled in theart, for I do not mean to limit my invention to the construction shown.

Vhat I claim as my invention is:

l. Ina carding engine, the combination with a carding cylinder and adolfer, of a rocking or swinging carrier pivotally mounted on theengine, a rotating stripping roll supported by said swinging carrier, anexhaust nozzle movable with said carrier and extending closely adjacentto said stripping roll, means for changing the working position of saidswinging carrier to cause said stripping roll to engage either saidcarding cylinder or said doifer, and means for locking said swingingcarrier in any desired position.
